Detection and Estimation of Ochratoxin A [PDF]

open access: yesNature, 1966
THE recent isolation1 of ochratoxin A from Aspergillus ochraceus Wilh., which has a widespread natural distribution, made the development of a rapid method for the detection and estimation of the mycotoxin desirable. The following methods have been used during screening of fungal strains and media for toxin production.

Efficacy of Ammonization to Eliminate Common Mycotoxins

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2022
Mycotoxin is a worldwide problem threatening animal health and performance as well as public health. The objective of this experiment was to test the effect of ammonization on elimination of common mycotoxins in laying hen compound feed (CF) and dairy ...

Biological control strategies of mycotoxigenic fungi and associated mycotoxins in Mediterranean basin crops

open access: yesPhytopathologia Mediterranea, 2012
Fungi that belong to the genera Aspergillus, Fusarium, and Penicillium pose serious phytopathological and mycotoxicological risks at pre-harvest and post-harvest stages, as well as in processed food products because they can produce several mycotoxins ...

The occurrence of ochratoxin A in coffee [PDF]

open access: yesFood and Chemical Toxicology, 1995
Ochratoxin A (OA) is a nephrotoxic and nephrocarcinogenic mycotoxin which is predominantly produced by the two ubiquitous fungal genera, Aspergillus and Penicillium. OA is found in foodstuffs, predominantly in cereals but also in coffee beans. Inconsistent results have been published regarding the influence of roasting on the OA content in roasted ...

Metabolism of ochratoxin A by rats [PDF]

open access: yesApplied and Environmental Microbiology, 1982
Albino rats were given ochratoxin A (6.6 mg/kg body weight) intraperitoneally or per os. Independent of route administration, 6% of a given dose was excreted as the toxin, 1 to 1.5% as (4R)-4-hydroxyochratoxin A, and 25 to 27% as ochratoxin alpha in the urine.

Review of mycotoxin reduction in food and feed: from prevention in the field to detoxification by adsorption or transformation [PDF]

open access: yes, 2011
Mycotoxins are secondary metabolites present worldwide in agricultural commodities and produced by filamentous fungi that cause a toxic response (mycotoxicosis) when ingested by animals.

Modeling Growth and Toxin Production of Toxigenic Fungi Signaled in Cheese under Different Temperature and Water Activity Regimes

open access: yesToxins, 2016
The aim of this study was to investigate in vitro and model the effect of temperature (T) and water activity (aw) conditions on growth and toxin production by some toxigenic fungi signaled in cheese.
